[0044] As Figure 1 、 Figure 2 and Figure 4 shown, the present utility model provides an integrated intelligent control system for preparing carbon nanotubes, which at least includes: a control cabinet 1, and at least one liquid supply device 3, an ultrasonic device 21, a liquid storage tank 2, and a sprayer controller 4 integrated in the control cabinet 1.
[0045] The liquid storage tank 2 is arranged at the bottom of the control cabinet 1; and the liquid storage tank 2 is connected to the input end of the liquid supply device 3; the liquid storage tank 2 can continuously supply liquid to the liquid supply device 3, as shown in Figure 1 and Figure 2 .
[0046] To improve the quality of the supplied liquid, a device with a stirring function can be installed on the liquid storage tank 2. Preferably, an ultrasonic device 21 is installed on the liquid storage tank 2, and the ultrasonic device 21 can generate vibrations to vibrate the liquid in the liquid storage tank 2, generating atomization, avoiding the phenomena of agglomeration and accumulation of the liquid in the liquid storage tank 2, and making the liquid relatively uniform. Thus, the liquid supplied to the liquid supply device 3 is relatively uniform and stable, thereby improving the quality of the prepared carbon nanotubes.
[0047] Preferably, the ultrasonic device 21 is installed on the side wall or bottom of the liquid storage tank 2.
[0048] Since the ultrasonic device 21 is installed on the liquid storage tank 2 and the liquid will generate atomization, no additional heating equipment is required. Therefore, compared with the traditional heating atomization method, it can reduce energy consumption, and thus the cost is reduced.
[0049] Reference Figure 2 , the liquid supply device 3 is suspended and installed in the control cabinet 1, and a stirrer 31 is installed on the liquid supply device 3, and a control element for controlling the injection rate and amount is installed on the output end of the liquid supply device 3; the output end is connected to a nozzle, and the nozzle is located in a reaction kettle (not shown in the figure) for preparing carbon nanotubes; the reaction kettle is connected to a protective gas system (not shown in the figure). Preferably, a pressure gauge (not shown in the figure) is installed inside and / or at the output end and input end of the liquid supply device 3.
[0050] Furthermore, the gas transported by the protective gas system to the reaction kettle is nitrogen, and a nitrogen gauge 14 for monitoring the nitrogen pressure in the protective gas system is installed on the control cabinet, see Figure 3 . A gas quick connector 15 is provided on the control cabinet, and the protective gas system is connected to the gas source through the gas quick connector, see Figure 3 .
[0051] The liquid enters the ultrasonic device 21 in the liquid storage tank 2 for vibration and then enters the liquid supply device 3. It is also affected by the stirrer 31 installed on the liquid supply device 3, which can make the liquid uniformly dispersed. Finally, it enters the reaction kettle through the nozzle and is dispersed in the protective gas in the reaction kettle. This uniformly dispersed liquid is conducive to forming a uniform carbon nanotube growth environment during the reaction process, thereby increasing the yield and quality of carbon nanotubes. The uniformly dispersed liquid has a large specific surface area, which can increase the contact area with the reaction gas, thereby improving its reaction activity. This helps to achieve the efficient preparation of carbon nanotubes at a lower temperature and in a shorter time.

[0056] The buttons 12 include buttons for adjusting air pressure, a power-on button, a power-off button, a button for closing the alarm, etc.
[0057] Some of the buttons 12 for adjusting air pressure can be used to adjust the pressure in the liquid supply device 3, and some buttons 12 are used to adjust the gas pressure in the reaction kettle.
[0058] Through the operating system on the control cabinet 1, various parameters can be set and / or modified, and the equipment status can be monitored. It has a high degree of automation and is easy to operate; at the same time, it reduces the fluctuations and unstable factors caused by equipment failures or operation errors; and it can ensure that the carbon nanotubes between different batches are consistent in morphology, size, performance, etc., improving the repeatability.
[0059] In another embodiment, the liquid supply device 3 of the present application includes at least one syringe 32. The liquid is transported to the reaction kettle through the syringe 32, see Figure 2 .
[0060] Preferably, the liquid supply device 3 includes two syringes 32, and the two syringes 32 are connected in parallel. Further, the stirrer 31 is installed on the syringe 32, see Figure 2 .
[0061] The use of the syringe 32 to deliver liquid can precisely control the input rate and amount. By adjusting the injection speed of the syringe 32 (such as 3 - 15 ml / h), the supply amount of the liquid can be controlled, thereby affecting the growth rate of carbon nanotubes and the quality of the fibers. The spinning state can be precisely adjusted to obtain an ideal carbon nanotube fiber structure and properties.
[0062] The liquid supply device 3 can be installed vertically, horizontally, or laterally, etc. Preferably, the liquid supply device 3 is designed to be installed vertically.

The fixed plate 51 is installed on the inner wall of the control cabinet 1; the movable plate 52 is detachably connected to the fixed plate 51 through fasteners, and the working surfaces of the movable plate 52 and the fixed plate 51 are opposite; the working surfaces of the movable plate 52 and the fixed plate 51 surround the syringe 32 and abut against the outer wall of the syringe 32.
